CONSTRUCTION OF INFORMATION SYSTEM UTILIZING SNOW DEPTH AUTO-MEASURING UNIT

To enhance highway service level in winter, it is most effective to clear snow from highways; however, at present, human judgment is still relied upon for deciding when snow plows should be dispatched. This paper describes a snow depth auto-measuring unit that enables staff to obtain objective data on highway surface as much as possible without going to the site. The unit can automatically measure snow depth, snowfall intensity, highway surface temperature, etc., with an infrared radiation sensor, and these collected data are displayed on the screen of a personal computer in the office or at home through the public telecommunications line. Consequently, the staff can easily observe latest meteorological data and road surface condition data, which are renewed every 15 minutes, and can dispatch snow plows to the site on time without fail. Further studies are being conducted on information systems that will provide highway surface information to drivers.
